Description

Technical Field

[0001] This utility model relates to the field of fire detector cleaning technology, specifically a fire detector cleaning tool that does not require disassembly. Background Technology

[0002] Fire detectors are commonly used monitoring devices to prevent fires from causing personal injury and property damage. To ensure the proper functioning of fire detectors, regular inspections are necessary. Over time, dust accumulates on the smoke-sensing parts of the detectors during normal operation, reducing the emission level and consequently decreasing the stability of the signal, significantly lowering the detector's sensitivity. Therefore, regular cleaning of fire detectors is also required. Since fire detectors are typically installed at the top, manual cleaning usually requires ladders, which is inefficient and carries the risk of damage due to improper handling by cleaning staff. Furthermore, this high-altitude cleaning work poses potential safety risks of falls and property damage.

[0003] Chinese utility model patent with publication number CN222358856U, entitled "A Fire Detector Cleaning Tool Without Disassembly", cleans fire detectors installed at high locations by setting a cleaning mechanism at the telescopic end of a multi-section telescopic rod. The cleaning process does not require disassembling the fire detector, effectively solving the problem of cleaning fire detectors.

In use, the nozzle 21 can be rotated around the damping hinge to be adjusted to a suitable angle for use.

[0026] Furthermore, the outer surface of the screw cover 2 is provided with anti-slip texture 22. The anti-slip texture 22 is evenly distributed on the outer surface of the screw cover 2, which can help to rotate and unscrew the screw cover 2 in a convenient way.

[0027] An air inlet pipe 11 is connected to the bottom of the hollow tube 1. The air inlet pipe 11 is connected to the inside of the hollow tube 1 and to the nozzle 21. A valve 111 is also installed on the air inlet pipe 11. The valve 111 is connected to the air inlet pipe 11. In use, the air inlet pipe 11 is connected to a high-pressure air source (air pump). After opening the valve 111, the high-pressure gas is immersed in the nozzle 21 and sprayed out through the hollow tube 1, connecting pipe 4, screw cover 2 and hose 211. The sprayed airflow can be used to clean the fire detector. In addition, flame-retardant electronic burning cleaning agent can also be used for cleaning. The cleaning machine is connected to the air inlet pipe 11, and the cleaning agent is sprayed out from the nozzle 21 to directly wash the surface of the fire detector.

[0028] To collect dust during air blowing or detergent and stains during cleaning, a collection cover 3 is provided. A collar 31 is welded and fixed to the bottom of the collection cover 3. Before the screw cover 2 is screwed onto the outer ring of the connecting pipe 4, the collar 31 is first placed on the outer ring of the lower part of the connecting pipe 4, and then the screw cover 2 is screwed onto the outer ring of the upper part of the connecting pipe 4. The screw cover 2 can be used to fix the collar 31 to the outer ring of the connecting pipe 4 and to position the collection cover 3 on the outer ring of the nozzle 21.

[0029] When using the air cleaner, the blown dust falls and is collected by the collection cover 3. The collected dust can be poured out when the cover is removed. The bottom side of the collection cover 3 is provided with a bottom tube 32 that communicates with its interior. The bottom tube 32 is also fitted with a sealing sleeve 321. When using cleaning agent to rinse, the sealing sleeve 321 needs to be removed first and the conduit connected.

Then, hold the rubber sleeve 12 of the hollow tube 1 with one hand and the handle 13 with the other hand for easy lifting and operation. Aim the nozzle 21 at the fire detector, open the valve 111, and allow high-pressure gas to pass through the hollow tube 1, connecting pipe 4, screw cover 2, and hose 211 into the nozzle 21 and be ejected. This allows the ejected airflow to clean the fire detector and... Dust blown off is collected by the collection hood 3. The collected dust can be emptied when the device is removed. Besides air cleaning, flame-retardant electronically charged cleaning agents can also be used. Connect the cleaning machine to the air inlet pipe 11, remove the sealing sleeve 321 and connect the conduit. Pump the pressurized cleaning agent into the air inlet pipe 11, causing it to spray from the nozzle 21, directly rinsing the surface of the fire detector. The cleaning agent washes away the dirt, which is collected by the collection hood 3 and finally discharged through the bottom pipe 32 and the conduit. When the device is not in use, the screw cover 2 and nozzle 21 can be easily unscrewed and removed using the anti-slip texture 22. This allows the collection hood 3 to be lifted and the collar 31 removed for easy storage. Alternatively, the screw cover 2 and nozzle 21 can be reinstalled for cleaning without using the collection hood 3.
